Why the lawn mower and a trimmer for the grass do not start possible causes and ways to eliminate them

If a trimmer for grass or a lawn mower is not started, then any desire to mow grass disappears. Very often, the owners of these tools face difficulties in starting a two.stroke or four.stroke engine after winter, when the tool was not operated for a long time. If this situation has occurred, then do not rush to take the tool for repair. Start finding a malfunction from less to larger, and with a 100% probability you will be able to start a benzotrimer engine. Where to start searching for a malfunction when the lawn mower does not start, we will consider step by step with all the details.

Hand starters are used to launch gasoline trimmers. Through such starters, manual movement of the crankshaft is carried out. At the same time, it is important to turn on the ignition so that when the crankshaft rotates, the fuel mixture entering the cylinder could be ignited. Inflammation of the first portion of the mixture will entail the launch of the engine, and at the same time the trimmer for the grass is ready to operate.

However, it often happens that attempts to start the engine come to naught. Naturally, when after 5 attempts to start the engine, it is not possible to achieve success, then you need to start diagnostic measures. There is a special sequence that should be followed to find the reason why the lawn mower is not started, and successfully eliminate it. The sequence of verification has the following format:

• Check the presence of fuel in the tank, as well as the quality of a mixture of gasoline with butter
• Determine the color of the spark plug, as well as signs of its functioning
• Make sure an air filter
• Check the fuel filter that is responsible for cleaning gasoline with oil entering the carburetor
• The serviceability of the sapun
• The reason that the lawn mower is not started, there may be a exhaust channel or muffler

It is these nodes that are the main sources of the problem of difficult trimmer for the grass. A more difficult problem is associated with a malfunction of the carburetor, which needs to be adjusted. Consider each node separately to find out the reasons why the trimmer for the grass does not start, and eliminate them with your own hands.

Do not understand why the lawn mower is not started, then initially make sure that there is a fuel in the tank. Often, beginners forget that it is necessary to periodically make pauses to season the tool with a gasoline mixture. If the gas mushroom tank is empty, then of course it will not start, no matter how much you try to do it.

If there is a fuel in the tank, but it is impossible to start the tool engine, then do not rush to disassemble the carburetor. Make sure that the trimmer engine is launched correctly, as indicated in the instructions. If the launch is carried out according to the instructions, then it is important to consider the following points:

• Use not just high.quality gasoline with the maximum octane number, namely the brand recommended by the manufacturer. And far from always such a brand is AI-95 gasoline. If you do not know which gasoline is used for the lawn mower, then choose AI-92
• The oil should be special. for two.stroke engines. If the lawn mower has a four.stroke engine, then pure gasoline must be poured into it without stirring with butter. On the quality of the oil for the engine engine, the grass should not be saved, as well as on gasoline. After all, the operational resource of the motor depends on the quality of the fuel used
• Proper preparation of the fuel mixture in a benzotrimer. Observations show that most mowers are only the first time control the process of cooking oil with gasoline for a trimmer for grass. The greater the experience of Kosar, the less close attention is paid to the process of mixing gasoline with butter for a two.stroke engine. The ratio of gasoline with oil should be the way the manufacturer recommends. Typically, this ratio is 25 to 1, that is, 1 liter of gasoline needs 40 ml of two.stroke oil (motor oil for the car and even more so you cannot use it)
• Proper storage of fuel mixture. It often happens that after the preparation of the fuel mixture, it costs for a long time for more than 2 weeks. It is impossible to store the finished mixture of gasoline with oil for a long time, as this leads to the fact that the oil is precipitated, and thereby the properties of both oil products are lost. Even thoroughly stirring after prolonged storage of the finished mixture is not a reason for its further use. That is why it is not recommended to prepare more than 2 liters of the mixture at a time

Make sure that all of the above points are made, and only after that you can start checking the condition of the candle. A trimmer for grass is not started for various reasons, and most of them can be identified independently. Resorting to disassembling the carburetor, if it is impossible to start the engine, is simply irrational. The next step towards finding a malfunction is a check of the state of the spark plug.

It is interesting!With prolonged storage of diluted gasoline with butter, these elements decay into heavy fractions. These fractions score not only the fuel filter of the tool, but also the carburetor channels. The maximum duration of fuel storage is no more than 14 days.

Why and what to do if a gasoline trimmer for grass does not start

If a benzotrimmer does not start, the breakdown can be caused by several reasons. Most often, the failure occurs:

• due to clogging of air or fuel filters;
• because of the exhausted old gasoline in the tank;
• due to damage to the fuel hoses;
• due to damage to the ignition system;
• due to a short circuit of the wires responsible for inclusion.

Also, the launch of the primer and the saapon, the clogging of the carburetor and the air damper drive clogged.

The most difficult thing is to repair a benzotrimer with a malfunction of the engine, but such a breakdown is rare

Exhausted gasoline in the tank

Many trimmers left fuel in the tank after using the unit. If the cover is not closed not, gasoline can exhale and absorb moisture from the air. As a result, the combination of the mixture is reduced, and the motor does not start.

It is very simple to fix the situation. you need to remove old fuel from a gasoline trimmer for grass. Do it like this:

• Pump up new gasoline primer.
• Twist the starter cable many times.
• Pump the old fuel through the combustion chamber until the tank is empty.
• Dry the candle.

You can also simply remove and disassemble the carburetor to drain the remnants of exhausted gasoline. But it is more difficult to do this, you must have minimal ideas about the device of a trimmer for grass that does not start.

A short circuit of wires

The wires suitable for the engine are responsible for the engine. they are connected by the switch, and as a result, the gasoline trimmer for the grass is launched. Due to poor-quality isolation or permanent vibrations, the cables can be wiped out.

If a short circuit occurs, the engine is not started by pressing the button. You can eliminate the problem according to this scheme:

• The wire departing from the start button is removed from the terminal terminal of the ignition system.
• Using the tester, check the cable resistance in “Inclusive” and “off” modes.
• If there is a malfunction, a working handle of a gasoline trimmer for grass is disassembled.
• Cut or solder suitable to the motor, ignition system and wire button.
• Extract the remains of cables and set new in their place.
• Collect the hilt back.

If the gasoline trimmer for the grass starts again, the repair was successful.

Attention! In good wiring during testing in “inclusive” mode should give resistance striving for infinity.

Flowing the air filter

If the trimmer for the grass has not stalled and does not start, the problem may consist in clogging an air filter. To diagnose a breakdown, you need to extract a candle from the unit case and inspect it. If there is clogging, it will be black.

To eliminate the problem, you need to disassemble the motorcycle and pull out the filter from the body. It is cleaned in accordance with the instructions for a specific trimmer for grass, and then set to place. To prevent the problem, it is recommended to conduct preventive maintenance of equipment from time to time.

Falf in the spark plug

If the benzotrimer does not start, the failure can be caused by a candle breakdown. Diagnosis is carried out as follows:

• Twist the element from the cylinder block head.
• Carefully examine. if the contacts of the candle will be covered with a malfunction, will be covered with a black coating.
• Soak the part in vinegar solution 20% for half an hour to clean.
• Sprinkled with soda and washed with water after another 30 minutes.
• Dry with compressed air and installed in place.

In some cases, after cleaning, the candle comes into an efficient state, and the gasoline trimmer for the grass starts again. If this does not happen, you need to replace the element with a new.

If a black fog quickly appears on the new candle, the problem may consist in re.enriched fuel

The ignition coil malfunction

If the trimmer for the grass is jerking off and does not start, it is worth checking the ignition coil. Do this as follows:

• All wires turn off the block and remove them from the candle.
• Measure the resistance of both coils-in the primary it should be 2-3 Ohms, in the secondary 4.5-5.5 ohms.
• With a strong deviation of the indicators, the ignition unit is replaced with a new.

You can check the knot in another way. Instead of a candle, the tip of the discharge is inserted into the appropriate wire and the latter is connected to the motor. Then you need to set a gap with a size of 0.5-0.8 mm and twitch the starter cable. The ignition unit requires replacement in the absence of a spark, but if it is, then the malfunction lies in the candle.

Recommendations and preventive measures

It is quite difficult to start a benzotrimer with malfunctions, sometimes repair requires a lot of costs and applies of efforts. Avoid breakdowns allows compliance with prevention rules. In particular, it is recommended:

• Timely clean the ribs of the starter and channels on the housing of a gasoline trimmer for the grass;
• Before a break in the operation of the unit, drain the remaining fuel from it;
• After cleaning the gas tank, start the engine at idle to eliminate the last traces of the mixture;
• use only high.quality fuel when operating the unit;
• load a gasoline braid in accordance with the instructions;
• Before cleaning for storage, disassemble and thoroughly rinse the trimmer for grass with solvents.

It is recommended from time to time to subject the gasoline braid to be careful to identify mechanical defects. Regular preventive cleaning requires air and fuel filters of the system.

Attention! Before cleaning the gasoline trimmer for storage grass, you need to lubricate the piston group with motor oil.

The more intensively the benzotrimmer is used, the more often its individual working nodes clog

Cycle: why the piston may not move inside the cylinder

The flywheel of a trimmer for grass, aka Magneto’s rotor with magnets, is fixed on the shaft with a key.

This is usually a reliable connection. Under the flywheel there is a sealing oil seal that does not pass the oil from the crankcase out. But when he wears out, the craftsmen have to remove the flywheel and change the oil seal with a new.

Otherwise, the oil flies everything, including the air filter.

At the same time, it is not so easy to remove the key: people make special pullers.

When looking for information on trimmers, I came across a video of one master, who was brought into the repair of the lawn mower, where the flywheel gap was absent. Perhaps a factory marriage. Naturally, such a motor will not start.

A similar reason should also be borne in mind.

Cycle: malfunctions of the sparkling spark

Когда поршень достиг верхней мертвой точки и сжал правильно подготовленную рабочую смесь вместе с воздухом, то ее поджигает электрическая искра, проскакивающая между контактами свечи.

Iskra is a category of electric current among gases. He must have a certain force and power. Weak spark of candles is not able to ignite the fuel mixture.

The causes of a bad spark should be sought in the electrical and kinematic scheme of its formation. magneto. This is the name of a device that transforms the mechanical energy of rotation of the shaft into a spark: current discharge.

Trimmers for grass and chainsaws are now supplied with a contactless electrical circuit of Magneto: it creates less problems in operation than a system with an interrupt. With her, the gas outlet starts more reliable,

• flywheel or rotor magneto with built.in constant magnets;
• high.voltage coil with wires and electronic circuit;
• spark plug.

During the repair, it must be borne in mind that the electrical electronics and candle design details can differ in various parts of the electronics, although manufacturers try to unify and standardize them.

The following picture will help to understand the principle of their work.

The constant magnetic field of the rotor rotates next to the high.voltage coil having control windings, power and charger. Each of them introduces its own electromotive force, which is the source of energy of electricity.

The output winding of the high.voltage transformer, running electronics, gives out the pulses of the discharge current to the spark plug, between the contacts of which the spark rides.

I used to see an old specialized device for checking the spark plugs in a sealed transparent case. Inside the unit, a pressure was created, a screwed candle was connected to an electrical circuit and checked on a spark.

However, each owner can check the power of a spark and the operation of a candle with a sparkling coil right on the trimmer:

• The candle is twisted with a candle key from the cylinder block;
• A high.voltage wire with a dielectric tip needs to be connected to the candle head. we restore the contact contact of the output winding of the transformer;
• The metal part of the candle body is laid on the cylinder block. You can use a conductive conductor. the same candle key. Only it cannot be inserted into the cylinder: you can damage the piston head;
• with a free hand it is necessary to pull evenly, but not pull, the starter cord. Visually observe the state of the spark on the contacts of the candle.
• contacts of the spark plug and the state of its insulation;
• the integrity of the high.voltage wire;
• serviceability of a high.voltage coil;
• the degree of wear of the permanent magnets of the flywheel;
• air gap between the flywheel and the ignition coil.

If the spark is weak or absent, then most often the causes of the malfunction lie in contaminated contacts or violation of the factory clearance of the candle. Other factors appear less.

When purchasing a trimmer for the grass, you need to take care of the reserve candle of the same brand. She, like spare parts, is needed when the motor does not start.

I recorded the brand my factory candle: l7t. You can use counterparts in case of breakdowns or damage when repair is required.

The candle gap of the non-contact ignition of the trimmer for the grass should be maintained in the interval of 0.7-0.8 mm. When examining and diagnostics, I recommend cleaning the contact electrodes from the carbon. Voronilo will help. a type of fine.grained file.

It is necessary to take into account the causes of malfunctions of the high.voltage coil and insulation of the wire. But they happen less often than that of a candle. If you noticed cracks, cuts, damage to the insulating layer, then wrap it with electrical signs, put on a heat shrink, or preferably replace it completely.

Magneto’s most overstated air gap can also be greatly affected by the lawn mowed. When it does not start, it should be reduced on its own to 0.2 mm.

This question clearly explains the owner of the video repair Nick TV in his video “A lawn mower or chainsaw, first prevention” is poorly started “. I recommend to see.

If you look at the lower part of the ignition coil, then a rectangular metal plate is visible in the middle.

It should be located on the central line of Magneto. Displacement forward or backward: it will be early or later ignition. The best performance is in the center. Seek minimal deviations. The settings are simple.

Where to start diagnostics motorcycles

If the lawn mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main nodes and assemblies. The test algorithm is as follows:

These nodes are most often source of basic problems, which can be eliminated after a thorough inspection.

Check the fuel mixture

Before starting the engine of a gasoline braid for grass, check the presence, and the quality of the fuel mixture. Do not save, do not greedy and “do not smarter” in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil fuel mixture strictly according to the instructions. Calculate its number from real needs. Excess gasoline left after work loses its qualities over time.

We diagnose a candle and candle canal

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be the reason. Here, a regular candle key is suitable for repair (every motorist has probably has a spare candle.

• We twist the candle and wipe;
• We thoroughly dry it (you should not bake it);
• Excess fuel in the chamber we drain through the candle hole and dry it;
• We clean the old candle from the carbon on a sugar or a ladies’ file;
• We set a gap with a distance of 1 mm (you can check with any coin);
• We return everything to place and try to start a trimmer for the grass.

Dry the channel at least 30-40 minutes. Otherwise, there is a risk of re.pour a new candle.

If the working candle is working, the nest, where it is located completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly moisturized. No matter what wonderful spark gives out a candle, there is simply nothing to light up in a dry chamber.

All the whole, clean, works?

We try to adjust. We take a long screwdriver, we find a bolt of idle speed adjustments (it is on the throttle), twist it a couple of revolutions so that the damper is opened. We start. It works smoothly? Then we go further. Does not start or stall? Open the damper until it starts stably.

Next, adjust the quality of the mixture with a screw l. You need to achieve maximum storage speeds. Here the principle is the opposite. the more the bolt is unscrewed, the richer the mixture. After that, the quality of the mixture at maximum revolutions by the screw h.

If the adjustment of the carburetor has not given its fruits, then it needs to be disassembled. Watch the membrane, clean nozzles and inner moves. For this, it is necessary not only to have a reptile, but also preferably a reserve carburetor.

Recommendations for storage of gasoline trimmer for grass in the offseason

Placing a trimmer for storage grass, it is worth filling the gearbox with a sufficient amount of oil. Then you need to clean the air filter, partly disassemble, blow and wash the unit engine. Having dried all the mechanisms, lubricate moving elements. To carry out the processing of the piston system with oils, you need to extract the spark plug for previously. The lawn mower will not start or start, but stalls. What is the reason? If there is no spark. Then it is necessary to move the piston to the extreme position, then pour an insignificant amount of oil into the candle hole and make a scroll of the crankshaft. If the gasoline trimmer for grass in the offseason is not planned to be stored in the house, it is recommended to tightly wrap the unit engine with an oiled rag. This will allow to avoid the development of corrosion on the surface of the fundamental nodes of the mechanism.

In order for the lawn mower to start well and continue to provide it with good storage and operation conditions:

• During operation, carefully monitor the cooling system, carefully and in time, clean the channels in the case, as well as the ribs of the starter;
• If necessary, use solvents, kerosene and other detergents for cleaning;
• Do not clean the “hot” tool. let it cool;
• Stactly comply with the requirements of the instructions for the operating mode, otherwise you can overheat the engine;
• If you do not plan to use the lawn mower in the next month, the fuel mixture from it needs to be drained, t. to. Over time, it breaks up into heavy fractions, which will definitely clog the channels of the carburetor;
• After draining the fuel, let the trimmer work at idle until it stalls, this will help to completely remove the rest of the working mixture.

Before winter storage, take the following steps:

• completely disassemble the braid, rinse and clean all the details you can;
• Inspect the details for damage, if necessary, eliminate distortions, impulses, bent and any other malfunctions;
• Pour a sufficient amount of oil into the gearbox and clean the air filter;
• You can partially disassemble the motor, rinse, blow and smear all the moving parts;
• In order to lubricate the piston, you need to unscrew the candle, raise the piston with the outlet to the extreme dead point, pour a little oil into the candle hole and scroll the crankshaft a couple of times;
• If you store the lawn mower not in the house, wrap the engine with an oiled rag.

Remember, careful compliance with the rules will allow you to forget that the lawn mower is bad for several seasons.

How easier to start a lawn mower? To do this, you need to know a few tricks

If your lawn mower starts up, but does it not as easy as we would like, we suggest using the following tips:

• Put the tool on the side so that the air filter is at the top. What will it give? The fuel mixture will fall exactly into the bottom of the carburetor. You can still remove the air filter and pour a couple of drops of the mixture into the carburetor and then install all the parts in place. The tool will start on the first attempt!
• Perhaps the problem is in the candle, and then, unfortunately, the previous method will not help. But there is another! Twist the candle, check it for performance and dry the combustion chamber. If the part does not show signs of life, replace it with a new.
• A universal advice that will help to start a lawn mower and a saw with a snowman. But it acts if the spark plug is working, the fuel mixture is fresh, air and fuel filters are clean. So, we close the carburetor damper and perform one movement by the starter. Next, open the damper and again twist the starter 2-3 times. We repeat the procedure, after 3-5 cycles the engine will begin to start.

The most frequent malfunctions of gasoline lawners

It is necessary to check the fuel. It is possible that due to its absence, the engine will not start. The reason for the refusal of the engine may be a candle. The car is removed and the engine is launched again.

Силовой агрегат завелся, но сразу заглох

The reason for the refusal of work may be an insufficient amount of oil in the motor crankcase. Because of this, the piston or crankshaft often jams. Try to hand it manually. Often such actions give a positive result. Then, before repeated start, it is necessary to add the missing oil.

To revive the unit, it may be enough only to pump up fuel with a plain in a carburetor. The speed adjustment to the maximum will help. Then pull the cord smoothly on yourself. Twenty centimeters will be enough and a sharp jerk jerk over yourself.

Often problems arise With improper location of the air damper

, when the first trial start of the motor is produced. It is recommended to completely open the damper.

can serve as an air filter. It is necessary to disconnect the wire from the spark plug on the disconnected lawn mower. Then remove the filter, having previously unscrewed the lid. Rinse it with gasoline and dry it. Put in place, carry out re.launch of the motor. If the actions are unsuccessful, replace the old filter with a new.

We remind you. the planned replacement of the air filter is carried out after 25 hours of operation of the equipment. If the lawn mower works on the battery, you need to check the level of its charging.

Can Check the safety lock

If the installation is carried out incorrectly, the lawn mower will not start. Experts advise regularly inspecting the lower surface of home appliances. Various malfunctions in this part may cause engine failure to work.

If your efforts are unsuccessful, contact the service center for the consultation and help of specialists who will be able to carry out any repair of the lawn mower, in particular it.

If the trimmer for the grass does not start, we check the serviceability of the filters

You will need to resort to checking the air filter, through which the incoming air is cleaned into the carburetor. The clogging of the cleansing element leads to the fact that the air enters in a smaller quantity or its supply to the carburetor is completely stopped. Find out whether the air filter is the reason that the trimmer for the grass is not started is in a simple way:

• Remove the air filter and inspect it. The presence of clogging is already a reason to blame this detail in everything
• If there are no clogs visually, then you must try to start the motor without a filter. If a trimmer for grass starts without a filter, then it is definitely necessary to replace this part
• The air filter can be cleaned with a stream of compressed air, but if it has not changed for a long time, it is advisable to replace it with a new

It should be noted that a trimmer for grass can not start due to a blockage of an air filter, but these are extremely rare cases. Often, air filter clobs affect the stability of the engine, and also contribute to a decrease in performance.

It is interesting!If the chainsaw began without an air filter, then working as a tool without a filter element is contraindicated, since pollution will fall into the cylinder, and thereby the operational resource will decrease. The real reason why the gasoline trimmer for grass is not started is to clog the fuel filter. This part is located in the tank of the tool, and if the spit is already more than 2 years, then it is time to check the serviceability of the fuel element. If the filter is clogged, then the fuel mixture will not enter the carburetor accordingly, which means that the trimmer will not start the grass.

There are no difficulties with the replacement of the fuel filter, since for this it is enough to extract this part from the tank, and to replace it. If you are going to clean the fuel filter with a compressor, it is recommended to abandon this venture. It is better to buy a new filter for cleaning the fuel of the lawn mower, since clogs will still remain inside the old element. Below the video shows the process of replacing the fuel filter on the Oleo-Mac brand gasoline.

If you are not sure that the reason for the impossibility of launching a trimmer motor for grass is a cleansing element of fuel, then the following actions should be done:

• Remove the fuel filter
• Run the lawn mower
• If she got started, and quickly, then the problem is really in the fuel filter

The filter is clogged through the following reasons:

• With prolonged operation of the tool
• If low.quality gas or oil is used
• With prolonged storage of fuel in the tank of the tool
• If you pour fuel into the tank, which was stored for a long time
• When dust and small particles get into the tank of the tool. This usually happens during the tooling

It is interesting!If the fuel filter is working, and the lawn mower is not started, then it is worth making sure that the fuel hose is placed in the fuel. After all, there are times when the hose, along with the filter, is simply disconnected from the trunk tube, which leads to the impossibility of starting the engine engine.

Typical malfunctions

The most frequent breakdowns arising during the operation of the unit are:

• the engine does not work, the trimmer is not started for grass;
• The engine manages to start, after which it does not hold back and stalls sharply and for no reason;
• The rod of the motorcycles vibrates greatly;
• The gearbox overheats greatly;
• Weak turnover at the cutting fishing line.

Before you start repairing, study the instructions that must be in the kit to correctly diagnose

And again the carburetor.

Well, even if after such bullying your trimmer does not start for the grass, you can’t do without disassembling the carburetor. It may very well be that everything is to blame for the gathering of the needle in it. In any case, the disassembly and washing of this capricious mechanism certainly will not hurt.

In general, when a trimmer for the grass began to be capricious and stall, it is advisable to carry out complete prevention: to completely change the fuel mixture, try another oil, and also mandatory change the candle. The gasoline trimmer for the grass does not start? Reasons and decisions on. Practice shows that in many cases, it is precisely cheap low.quality candles that are to blame.

We examined the most typical reasons why a trimmer is not started for grass. If the matter is something more “exotic”, do not pass the campaign in the service center. You will probably find smaller and obvious breakdowns yourself.

Why is a trimmer not starting for the grass: the main malfunctions and their elimination

As already noted, such situations are characteristic of trimmers who were inactive for a long period of time. Therefore, after detecting the problem, you need to immediately take up the search for a malfunction.

Fuel as source of problems

The first stage is checking the presence of fuel and its quality. First of all, they are convinced that there is a fuel in the tank. Those who have acquired the unit recently, often forget that the trimmer for the grass needs refueling. If there is no fuel, then the equipment simply cannot work.

If there is a fuel in the tank, but the trimmer does not start for the grass, then the owner needs to check whether he is acting correctly. In this case, it is recommended to study the instructions. If the launch is made correctly, then the malfunction can cause the inappropriate quality of the mixture.

• Oil. It should be special. intended for two.stroke engines. It is not recommended to save on the product, since the life of the equipment depends on the mixture. Trammers for grass with a four.stroke engine require pure gasoline, it is not mixed with butter.
• It is necessary to use not only high.quality gasoline, but also the brand that is recommended by the manufacturer of a particular model. If it is not possible to find out what fuel is necessary, then it is recommended to choose either AI-95 or AI-92, and the last gasoline is a favorite, since the first has additives that react with two-stroke oil. Other brands do not advise using.
• The correct preparation is shifted for a benzotrimer. It is noted that at first this stage is paid to maximum attention, but over time, kosari begin to mix the composition “by eye”, and this is already a serious mistake. The correct ratio of gasoline and oil is 25: 1. For a liter of the first, 40 ml of the second, two.stroke. Motor oil intended for a car is an inappropriate option, since at high temperatures the liquid loses (partially) lubricating properties.

The correct storage conditions of the fuel mixture are important. To save time, some owners prepare it for the future to use it in the coming weeks. This option is contraindicated, since the prepared fuel mixture quickly becomes unsuitable. The reason is the precipitation of oil loss. With this change, both oil products lose their properties. Even repeated stirring is not able to restore the initial quality of fuel. Therefore, they recommend preparing a certain volume: 2 liters, no more.

If everything is in order with gasoline and oil, then they start diagnostics. to check the spark plug.

Candle and its condition

At this stage of diagnosis, you need to stop in more detail. Most experienced owners who are already familiar with the question of why a trimmer for grass does not start, first of all check the state of contact contacts. Diagnosis of this element is carried out as follows:

• First, the spark plug is unscrewed, then inspect. If the electrodes are in perfect condition, then they should have a carpet whose color resembles a brick. Wet element, or white, black plaque on contacts indicates the presence of any malfunction. Pink and red electrodes. proof of a large number of additives in fuel. Such a mixture must be replaced.
• In the event that the spark plug is wet, this means that the combustion chamber has unbroken fuel. It is left in place. Candle contacts are cleaned, then dried (calcination is prohibited). After this stage, the candle is connected to the nurser.
• Then the ignition is turned on, the frontier handle is pulled. When everything is in order with the element, it must issue a constant spark. If it is weak or completely absent, then the verdict is one. you need to replace the spark plug.

There is another reason why a trimmer is not started for grass. This is a big gap that appeared between the contacts of the candle. A distance of 0.7-1 mm is considered normal. To correctly adjust the gap between the electrodes, use special probes.

If there is no such device, then the folk method is used. A razor blade breaks, folds its parts together. Then this “probe” is inserted between the contacts. Ideal. blades that enter tightly.

The problem is in the fuel and the carburetor
